11// ExposureWidgetis a subclass of QDoubleSpinBox.
12// It has been created for use with the Focus exposure field. This field has been extended to allow exposures
13// as short as 0.00001s. To keep consistency with the exposure field in Capture only 3dps are displayed by
14// default, e.g.:
15// 2 is displayed as 2.000
16// 2.1 is displayed as 2.100
17// 2.001 is displayed as 2.001
18// 2.0001 is displayed as 2.0001
19// 2.00001 is displayed as 2.00001
20//
21// This header file is linked into QT Designer using the Promote widget approach so that ExposureWidget rather than
22// QDoubleSpinBox is used.
